A gear wheel 15 is journaled on the axle and maybe connected thereto by a clutch '16. The clutch is operated by a lever 17, piyoted at 18 on a toothed'segmsiit' 19 rigid with the frame, and having an angular fork To all whom it may concern:

Drvnv, Jr, and \VALTER AVERY Driver, citizens of the United States,.and residents of Lel'ii,-county of Utah, Garland, county of Bcxelder, and American Fork, county of Utah, in the State of Utah, respectively, have invented certain new and useful Improvements in Beet Toppers and Diggers,

groove '21 in the movable part of the clutch.

the usual catch 22 slidable onthe lever and operated by a latch lever 23 A pair of spaced arms 24 are ,journaled onthe axle, and each arm is provided at its freefend with a bearing25, in which'isjon naled a counter shaft 26. Afpinion 27 on the outer end of ,theshaft meshes with-the gearv wheel 15, and-a bevelgear' 28 is secured to the shaft between the arms.

A shaft. 2!) is journaled longitudinally of the frame, on cross bars 30, that connect a pair of spaced bars Ill, and with the said bars form an auxiliaryframe, having at its lower forward end a block ?2. The rear end of each bar Ell journaled 0n the counter shaft 26 before n'ientioned. A cutting dislri-lS is journaled on'the block, by means of a cap screw .l-t, having a plain portion for receiving the-hearing of the disk, and a, threaded portion engaging a threaded opening in the block. '.Thc'a l.jacent-end.of the shaft 29 is provided with a bevel gear meshing with a ring-36 of bevel gear teethon. the under face of the disk, and a hall hearing 37 is arranged between the rear face of the disk and the block. A. fender plate is arranged behind the cutting disk, in an inclined position, and the said plate has an opening 39 for theshaft 29.

An arm 4-0 is connected with each of the hars 31 of the auxiliary frame, and each of the arms is lapped at its front end on the adjacent. bar, and the edges of the arm are bent over upon the opposite face of the bar, as shown at ll. Each arm isoti'set upwardly at 49, and extends on the opposite side of the axle from the frame. A weight 43 is Slidabloon each arm, and is held in adjusted position by a set screw -14. weights are intended to counterbalance the auxiliary frame, and its attachment, and may be adjusted for the purpose. An arch bar 45 is secured to each of the bars 31 near its front end, and extends upwardly and ()ur invention is an improvement in beet toppers and diggers, and consists in certain novel constructions and combinations of parts, hereinafter described and claimed.

The object of the invention is to provide a simple and easily operated device of the character specified, especially adapted for harvesting sugar beets, which will first top the beets while yet firmly held in the soil, and will aitterward dig them.

Fig; lis a section on the line l-4. of Fig. 2. Fig. 5 is a perspective view of a-portion of the adjusting mechanism for th'erollers. Fig. 6 is a plan view of the roller axle, and, Fig. 7 is a section on the line 7- 4 of Fig. 2.

' .The present embodiment of the invention an im n'men'ient over our prior Patent 5o. 975218, dated lioveniher 8th, 1910, and

parallel side plates 1 and The front end i and 2 respectively of each .of the side plates 1 and 2 is off-set inwardly and is connected to the tongue 3. -i\ brace 4 con-- meets the bars at the rear ends of the offset portions, and cross bars 5 and 6 connect the plates intermediate their rear ends and the lance. An axle? is journaled transversely of the frame in hearings 8 on the plates l and 2, and wheels 9 are journaledon the ends of the axle, and connected thereto by a pawl and-ratchet mechanism, (Fig. 7). A ratchet wheel 10 keyed-to each end of the axle by a key 11, inside the hub 12 of the adjacent wheel, and a plurality of pawls 13 are pivoted to the hub, and are pressed against the ratchet wheel by springs 14. The arrangement is such that when the wheels are rotating in a forward direction, the axle is carried therewith, while when the wheels are rotating rearwardly, the pawls slip idly over the teeth of the ratchet wheel.

and the lower end of each bar is longitudinally slotted at 48.

A crank shaft 49, shown more particularly in Fig. 6, is arranged between the bars 47, and each end of the crank shaft is cut away at opposite sides to form a flattened portion 50 for moving in the slot. The extremities of the shaft are threaded at 51, and a link 52 provided with an opening for receiving the threaded portion, is arranged at each end of the shaft, outside of the adwith respect to the arms 58.

arms 58 and (31 is provided with a hub 62,

jacent arch barti'. The crank shaft a9 is divided into three bearing portions or journal pins, of equal length, by the crank The crank forms one of the said portions, and since the crank is at the center of the shaft, a similar portion is formed on each side of the said crank. A roller is journaled on each of the said portions, and the shaft is held with the crank extending forwardly, so that the central roller 5A is always in, advance of the side rollers 55.

.The roller 54 is sectional, as shown in Figs. 3' and 4, and the sections are held on the shaftby bolts 56. Nuts 57 engage the ends of the crankshaft to hold the parts in place, and each of the links is pivotally connected to an arm 58, extending forwardly from a shaft 59, by means of a bolt (30. The shaft 59 is square in cross section, and an arm 61. extends upwardly from the center thereof, and at an angle of 90 Each of the having an opening to fit the shaft. A lever C3 is pivoted at Get on a bracket 65 on one of the slde bars of the auxiliary frame, and

' the bracket is provided with a notched segment G6, engaged by a tooth (37 on the lever to hold the sail lever in adjusted position.

The, tooth is operated'by a grip (38, and the lever is connected to the arm 61 by a link 69. It will be evident that when the lever is swung, the shaft 49 will be raised or lowered, moving in and guided by the slot 48 of the arch "bars 47. A bracket 70 is connected with the upper edge of the portion 2 of the plate 2, and a lever 71 is pivoted to the bracket. The said bracket has a notched segment 72, and a tooth 73 is slidableon the lever and engages the notches of the segment. The tooth is operated by a latch lever 74-.

The lever is provided with a lateral arm 75 at its lower end, and a chain 76 connects the said arm with a lateral lug 77 on the adjacent arch bar 17. By moving the lever 71 in the proper direction, the arch bars and the auxiliary frame may be raised or lowered, without changing the position of the crank shaft.

A seat 78 is supported nearthe axle, by

means ofa spring plate 79, and a turning a main frame, an axle journaled trans-- vrrsely thereon,.wheels on the axle, arms secured to the axle and extending forward therefrom, a shaft journaled in the free ends of the arms, an auxiliary frame pivoted at its rear end on the said shaft, a shaft journaled on the auxiliary frame at rightangles to the first-named shaft, a driving connection between the first-named shaft and the axle, a driving connection between the first-nan'icd and last named shafts, a disk cutter journaled at the front end of the auxiliary frame on a substantially vertical axis, said cutter having an annular series of gear teeth on its under face, a bevel gear ,on the last-named shaft meshing with the gear teeth of the cutter, and means for raising and lowering the front end of the auxiliary frame.
